Research Interests

Dr. Zhang's research focuses on coastal response to sea level rise and storm impact, airborne Light Detection and Ranging (LiDAR) remote sensing, storm surge modeling, and mapping coastal hazards using geographic information systems (GIS). He has authored and coauthored about 80 journal papers, book chapters, conference proceedings, and other publications. Specific areas of research include:

  • Development of algorithms to automatically identify ground and non-ground points and to extract three-dimensional shapes of buildings and trees from LiDAR measurements
  • Development of Coastal and Estuarine Storm Tide (CEST) model for depicting hurricane evacuation zones and real-time surge forecasting
  • Development of georeferenced, three-dimensional, visualization and animation platforms for hurricane-induced flooding and wind damage
  • Examination of long-term trend and interdecadal variations in the number and severity of coastal storms using water level records from tide gauges
  • Analysis of long-term and storm-induced beach erosion using shoreline position data from LiDAR measurements, GPS surveys, aerial photographs, and historical T-Sheets
  • Analysis of the inundation processes of storm surge and sea level rise and their impacts on real property and population
  • Estimation of the surface roughness using remote sensing data
  • Examination of the interaction between storm surge, wave, and vegetation
